During October 2025, Dusk enhanced bell notification functionality for the ghostty-org/ghostty repository by implementing a system beep for macOS users, providing clear auditory feedback when notifications occur. This feature was developed using Swift and Zig, leveraging macOS system APIs to ensure reliable integration. Dusk also updated cross-platform documentation to clarify bell behavior across different operating systems, reducing user confusion and support requests. The work included thorough testing and documentation updates to maintain a consistent user experience. While no bugs were fixed during this period, the focused feature delivery demonstrated depth in macOS development and commit-driven engineering practices.
